While the Fantastic Beasts movies are nowhere near as popular as the original Harry Potter series, fans of JK Rowling’s Wizarding World are still very much open to exploring Hogwarts’s history even deeper. Especially as they've begun to notice some clever callbacks to the original series.

One scene from Fantastic Beasts: The Crimes of Grindelwald, which was even featured in the trailer, shows Jacob Kowalski (Dan Fogler) looking extremely confused as the group arrives at Hogwarts. A Redditor recently pointed out:

“In this shot, Jacob is in the background, looking around and his expression denotes confusion. At first I was like: 'Well, of course he is confused! It’s not every day that you get to see the magnificent castle of Hogwarts.' Then I rewatched the trailer and I remembered: In [Harry Potter and] the Goblet of Fire, Hermione explains why magical schools have such a secrecy about their locations. She tells Harry that Hogwarts has a magical protection surrounding it, an illusion that makes Muggles see some devastated scary ruins to keep them away.”

It’s a small detail we don’t have actual confirmation on, but it would make sense based on the information we have from the original Harry Potter series. And given that Rowling wrote the script for Fantastic Beasts: The Crimes of Grindelwald, this seems like a pretty clever Easter Egg.
